1999 Dodge Ram V8 Two Wheel Drive Automatic 167000 miles
I recently have had random shutdowns while driving my truck. Driving along at 55 mph and all the sudden a loss of power. Pull over to the side. I turned key off then on again and it started.
A few blocks down the road it did it again very quickly though. It lost power (like not getting fuel) slowed down and then it came back and I continued on to the gas station. I thought fuel problem (3/4 of tank of gas) so I got some STP gas treatment at the station.
No problems for a couple of days and then all of the sudden it did it again. This time it would not come back on. I was thinking fuel pump. But I noticed something strange. When I would turn the key to the ON position all the gauges (gas gauge / oil gauge / battery gauge) would move a little but go back to the flat position. This made me think it was some sort of electrical or relay problem. I opened the hood and found the relay box and just gently tapped on the top of the relays etc.
I got back in the car and when I turned the key to the ON position all my gauges were working (coincidence? ). The truck started and worked fine.
Is there something other than a relay that can cause this kind of symptom. If the Relay is bad would it cause the fuel gauge to not respond?
Checked the Relays, and under the box I don't see any corrosion or anything that is loose.
When problem happened last time:
1) Lost power (like out of gas)
2) would not start but starter would crank.
3) Gauges. Fuel gauge would not register fuel but power was going to the gauges. When I turned the ignition to on the fuel gauge would rise 1/8th of an inch but then drop back down. After messing with relays etc (about 5 minutes). I turned Ignition to On and the gauge worked and then the truck would start.
That was yesterday and it has not happened since.
After reading your message, I am wondering if it is electrical. Is their something under the dash or in the steering column that if it were to short would cause the symptoms I have described?
If the fuel pump is bad will you still have fuel reading on the dashboard gauge? Or is that controlled by a different mechanism?
have the same problem?
